天津大虹桥南岸引线斜立交桥是建在弹性地基上的钢筋混凝土框架结构,桥址位于7度地震区,地基上层为填土和亚粘土,距地面以下约12m深有一层2m左右软塑性轻亚粘土。桥顶层公路面全宽30.30m,其中车道宽24m,按6车道汽—20、一辆挂—100设计,一辆挂—150验算,两侧人行道荷载为400ks/m~2;下层框架内行车道宽7m,两侧人行道宽各1.5m,均
The overpass at the south bank of the Hongqiao Bridge in Tianjin is a reinforced concrete frame structure built on an elastic foundation. The site of the bridge is located in a seismic zone of 7 degrees. The top of the foundation is filled with earth and clay, and about 12m below the ground, there is a layer of about 2m of soft- clay. The total width of the road at the top of the bridge is 30.30m, of which the lane is 24m wide. The design is based on 6-lane steam-20, a hanging-100 design and a hanging-150 checking. The sidewalk load on both sides is 400ks / m ~ Road width 7m, wide sidewalks on both sides of the 1.5m, are
